Also, a high corrosion resistance rust prevention paint containing these Zn alloy particles and a high corrosion resistance steel material and steel structure coated with that paint.

TECHNICAL FIELD

The present invention relates to Zn alloy particles for high corrosion resistance rust protection paint having physical fracture facets and/or cracks and imparting remarkably superior high corrosion resistance and rust protection, a method of production of said Zn alloy particles, a high corrosion resistance rust protection paint containing said Zn alloy particles, a high corrosion resistance steel material coated with said paint, and a steel structure having said steel material.

BACKGROUND ART

As a countermeasure to corrosion of ferrous metal materials, much use has been made of zinc-rich paints made using a zinc powder containing unavoidable impurities as a pigment and organic materials and/or inorganic materials as a vehicle (liquid binder ingredient).

Zinc-rich paints are mainly used as primers for heavy duty corrosion protection paint. The corrosion protection mechanism features the sacrificial corrosion protection of the zinc powder contained in a coat.

Further, the corrosion protection of a coat of a zinc-rich paint is strongly dependent on the extent of the sacrificial corrosion protection of the zinc powder, so depending on the usage environment, the rate of consumption of the zinc sometimes becomes larger and the corrosion protection on the ferrous metal material will not last long.

Therefore, in the past, the practice has been to increase the content of the zinc powder in the coat or increase the coat thickness, but as a result a drop in the adhesion with the surface of the steel material, cracking or sagging of the coat, etc. easily occur.

In the end, it is difficult to realize both the corrosion protection performance of the coat and the physical properties or coating ability. Measures increasing the content of the zinc powder in the coat are not perfect.

In view of this situation, development of a high performance zinc-rich paint able to maintain the advantages of conventional zinc-rich paints and furthermore exhibit a sacrificial corrosion protection over a long period of time has been hoped for. Up until now, various proposals have been made.

For example, Japanese Patent Publication (A) No. 59-52645 and Japanese Patent Publication (A) No. 59-167249 propose an organic-based zinc-rich paint containing not only a zinc powder, but also a Zn—Mg alloy powder, while Japanese Patent Publication (A) No. 59-198142 proposes an organic-based zinc-rich paint containing not only a zinc powder, but also a Zn—Mg alloy powder and Mn powder.

Furthermore, Japanese Patent Publication (A) No. 1-311178 discloses the long lasting corrosion protection performance of a Zn-(5 to 15%)Mg alloy powder in an organic paint, while Japanese Patent Publication (A) No. 2-73932 discloses the long lasting corrosion protection performance of an organic coat containing an Zn—Mg alloy powder with a metal structure comprised of Zn and MgZn₂.

Further, Japanese Patent Publication (A) No. 11-343422 proposes a rust protection pigment for an organic-based corrosion resistant paint containing flake-shaped particles of Zn alloy containing Al, Mg, etc.

In addition to the above, Japanese Patent Publication (A) No. 2001-164194 proposes an organic-based zinc-rich paint obtained by crushing an ingot of Zn—Al—Mg-based alloy powder where over 50% of the alloy powder is an Al/Zn/Zn₂Mg eutectic structure, while Japanese Patent Publication (A) No. 2005-314501 proposes an organic-based paint for improving the corrosion resistance of cut parts of a high corrosion resistance galvannealed steel material containing a powder of a Zn—Al alloy containing Mg or Si, having a spherical or oval shape, and having a value of the ratio of maximum size and minimum size (maximum size/minimum size) of 1 to 1.5.

The above proposals try to improve the corrosion protection performance of an organic-based paint and the corrosion resistance by the combination of a new alloy powder.

However, a general organic-based paint has the secondary problems of deteriorating in a composite environment of UV rays, moisture, oxygen, etc. and requiring maintenance in relatively short cycles.

In such a situation, several proposals have been made up to now for the purpose of improving the corrosion protection performance of inorganic-based paints not having such defects of organic-based paints.

For example, while different in object from the present invention, Japanese Patent Publication (A) No. 61-213270 proposes a paint composition containing a mixture of a zinc powder and Mg or Mg alloy for the purpose of inhibiting paint deterioration at the time of welding and cutting.

On the other hand, Japanese Patent Publication (A) No. 2000-80309 proposes a corrosion resistant paint having three types of phases, a Zn phase, Zn—Mg alloy phase, and Zn and Mg solid solution phase, as main ingredients and having these mixed in inorganic-based paint as powder particles and a corrosion resistant ferrous metal material coated with this paint.

The proposal of Japanese Patent Publication (A) No. 2000-80309 is noteworthy as being a fundamental means for improving corrosion resistance, but according to studies of the inventors, there are actually both cases where the corrosion resistance is improved and cases where the improvement in the corrosion resistance is not clear. There are questions as to the stability of the effect of improvement of the corrosion resistance.

Further, Japanese Patent Publication (A) No. 2002-285102 and Japanese Patent Publication (A) No. 2005-336431 propose an inorganic-based corrosion resistant paint containing flake-shaped particles of a Zn alloy containing Mg etc. and a corrosion resistant ferrous metal material coated with that paint.

However, including the proposal of Japanese Patent Publication (A) No. 11-343422, in the above proposals, the particles have flake shapes, so the new problem is caused that spray coating is difficult.

DISCLOSURE OF THE INVENTION

The present invention has as its object the provision of Zn alloy particles for high corrosion resistance rust protection paint having coatability and economy able to impart unprecedented, long lasting superior corrosion resistance and rust prevention to a ferrous metal material etc., a method of production of said Zn alloy particles, a high corrosion resistance rust prevention paint containing said Zn alloy particles, and a high corrosion resistance ferrous metal material and steel structure coated with that paint and as a result greatly extended in maintenance cycles.

The inventors engages in various studies and as a result newly discovered that non-flake-shaped particles comprised of Mg in 0.01 mass % to 30 mass % and a balance of Zn containing unavoidable impurities and having physical fracture facets and/or cracks exhibit remarkably superior corrosion resistance, rust protection, and coatability. This discovery is a discovery forming the basis of the present invention.

Furthermore, the inventors studied in detail the possibility of further improvement of the corrosion resistance and rust protection of said particles having physical fracture facets and/or cracks and as a result discovered that if the Zn alloy particles having physical fracture facets and/or cracks contain, by mass %, one or both of Al: 0.01 to 30% and Si: 0.01 to 3%, a more superior rust protection is exhibited and, further, that by arranging one or more of MgZn₂, _(MgZn) ₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃ at the fracture facets and/or cracks, a more superior corrosion resistance is exhibited.

The inventors also simultaneously studied the shapes of particles after fracture and as a result discovered that when the number of facets of an aspherical polyhedron after fracture is two facets or more, the self dissolution can be further reduced without impairing the rust protection performance, that is, the sacrificial corrosion protection effect.

Further, the inventors studied the size of cracks and as a result discovered that if the length is 0.01 μm or more or the depth is 0.01 μm or more, the corrosion protection is remarkably improved.

The mechanism of improvement of the corrosion resistance when the particles have surface cracks is not clear.

The fact that if there are cracks in the particle surfaces, the surface areas of the Zn alloy particles become larger and an Mg solid solution phase and intermetallic compounds easily form at the crack surfaces and, further, that the activity of the Zn alloy particles themselves is improved are believed to be part of the reasons for the improvement of the corrosion resistance, but effects beyond what is expected to be caused by these are exhibited. In the final analysis, the details are unclear.

Further, the inventors studied means for obtaining particles having fracture facets and/or cracks.

As a result, the inventors discovered that rather than obtaining fractured pieces by a ball mill, beads mill, or other means used as general fracture methods in the past, making the primary particles impact each other or making particles impact with a solid so as to obtain particles having physical fracture facets and/or cracks with more superior corrosion resistance and rust prevention and, furthermore, making the primary particles disperse in a solvent to obtain a slurry and make them impact and fracture, particles having physical fracture facets and/or cracks can be obtained with a good work efficiency without impairing the superior corrosion resistance and rust protection.

The Zn alloy particles having fracture facets and/or cracks give a superior corrosion resistance and rust protection even if used as is as a pigment for a paint, but the inventors engaged in further studies and as a result discovered that if using these mixed together with the Zn particle pigment generally used as a pigment in the past, a remarkably superior corrosion resistance and rust protection are given compared with a pigment using Zn particles alone.

Furthermore, the inventors discovered that when using Zn alloy particles having fracture facets and/or cracks to make a paint, if mixing the particles of the present invention as a pigment in an organic paint, an unprecedented superior corrosion resistance and rust protection are imparted even under a harsh composite environment of UV rays, moisture, oxygen, etc.

BEST MODE FOR CARRYING OUT THE INVENTION

The high corrosion resistance Zn alloy particles of the present invention contain Mg: 0.01 to 30% and have a balance of Zn and unavoidable impurities, have physical fracture facets and/or cracks, have an average particle size of 0.05 to 200 μm, and have an aspect ratio of the maximum size and minimum size (maximum size/minimum size) of 1 to 1.5.

In the Zn alloy particles of the present invention, Mg has to be 0.01 to 30%.

When having physical fracture facets and having an average particle size of 0.05 to 200 μm, even if Mg is less than 0.01%, a significant improvement is recognized in the corrosion resistance and corrosion protection compared with Zn alloy particles not having physical fracture facets and containing the same amount of Mg, but the remarkable effect of improvement of the corrosion resistance and corrosion protection expected due to the combination with the physical fracture facets and/or cracks is not obtained.

That is, the remarkable effect of improvement of the corrosion resistance and rust prevention due to the Zn alloy particles having physical fracture facets and/or cracks and containing Mg in 0.01% or more, that is, the remarkable effect of improvement of the corrosion resistance and rust prevention due to the synergistic effect of the physical fracture facets and/or cracks and the 0.01% or more Mg, is the basic technical idea of the present invention.

If Mg is contained over 30%, not only is the effect of improvement saturated, but also the economy and production efficiency are impaired, so the Mg was made 0.01% to 30%.

Here, the optimum value of the amount of Mg changes depending on the average particle size. In general, in the case of an average particle size of 0.2 to 30 μm considered optimum in spray coating, making the lower limit 0.1% and the upper limit 20% is preferable from the viewpoint of the effect of improvement of the corrosion resistance and corrosion protection and economy.

Furthermore, if considering the production stability, economy, and corrosion resistance, the amount of Mg is preferably 0.2 to 15%.

The “physical fracture facets” referred to in the present invention mean facets of shapes formed by parts of the spherical particles being removed. By the Zn alloy particles having physical fracture facets, as explained later, the effect of improvement of the corrosion resistance and corrosion protection is remarkably obtained.

Further, the “cracks” referred to in the present invention means cracks present on the spherical particle surface having a length of 0.01 μm or more or a depth from the surface of 0.01 μm or more. When the cracks have a length or depth of less than 0.01 μm, a sufficient corrosion resistance improvement effect is not obtained. A length or depth of 0.01 μm or more is required.

The average particle size of the Zn alloy particles is made 0.05 μm or more to secure the adhesiveness required at the time of spray coating and is made 200 μm or less to secure the work stability at the time of brush coating. If considering the coating stability, 0.2 to 50 μm is preferable. Further, if considering the coat adhesion, 0.2 to 30 μm is preferable.

The aspect ratio (maximum size/minimum size) of the particles was made an average value of 1 to 1.5 to secure coatability.

When predicated on spray coating, if the aspect ratio of the particles is over 2, the particle spraying and flight stability falls and the coat thickness and particle distribution stability in the coat falls.

If there are physical fracture facets and/or cracks on the particles, their stability falls somewhat, so considering this, the aspect ratio of the particles was made an average value of 1 to 1.5.

Therefore, even if particles with an aspect ratio exceeding 1.5 are partially present, they do not pose a problem.

Furthermore, the above range of the aspect ratio defines the Zn alloy particles in the material state and does not define the shape of Zn alloy particles in the case of absorbing the moisture etc. in the air and coagulating and coalescing before actually being used mixed in the paint or Zn alloy particles in the case of coalescence of particles cured on the steel material as a coat.

Further, at the time of production or storage, small relief shapes form at the Zn alloy powder surface, but the changes in shape due to these are not out of the range of spherical or oval shapes with an average value of the aspect ratio of 1 to 1.5.

Furthermore, the particles of the above constitution of the present invention may contain one or both of Al: 0.01 to 30% and Si: 0.01 to 3%.

If adding Al to the particles having physical fracture facets and/or cracks in an amount of 0.01% or more, the rust protection is further improved.

If making the amount of Al 0.01% or more, in addition to the rust protection, the corrosion resistance against self corrosion of the particles is remarkably improved, but even if added over 30%, not only does the effect become saturated, but also it becomes difficult to form physical fracture facets and/or cracks in the metal particles, so the amount of Al was made 0.01 to 30%.

Furthermore, from the viewpoint of production stability and corrosion resistance, the amount of Al is preferably 0.5 to 20%. Furthermore, if considering economy, 1.0 to 10% is preferable.

Si similarly improves the rust prevention if added in an amount of 0.01% or more to the particles having physical fracture facets and/or cracks. However, if adding Si over 3%, the rust prevention conversely deteriorates, so the amount of Si was made 0.01 to 3%.

From the viewpoint of production stability and corrosion resistance, the amount of Si is preferably 0.5 to 3%. Furthermore, if considering economy, 1.0 to 1.5% is preferable.

In the Zn alloy particles having physical fracture facets and/or cracks of the present invention, by giving the surfaces of the particles including the fractured parts and/or cracks an Mg solid solution phase and Zn—Mg intermetallic compounds, the corrosion resistance and the rust prevention are further improved.

The reason why the exposure of the Mg solid solution phase and Zn—Mg intermetallic compounds at the particle surfaces causes an improvement in the corrosion resistance and rust prevention is not clear, but the inventors confirm experimentally that if one or both of these phases coexist at the fracture facets and/or cracks, the chemical properties of these phases change to ones more preferable for improvement of the corrosion resistance and rust prevention and the corrosion resistance and rust prevention are stably improved.

The Mg solid solution phase and Zn—Mg intermetallic compounds can be identified by analyzing the ratio of composition of Mg and Zn of the surfaces of the physical fracture facets or cracks by observation by the X-ray diffraction method or a scanning electron microscopy equipped with an energy dispersion type X-ray analyzer.

In the present invention, by including, as said intermetallic compound phase, at least one type of compound of MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃, the corrosion resistance and the rust prevention are improved more.

MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃ can be identified by analyzing the ratio of composition of Mg and Zn of the surfaces of the physical fracture facets or cracks by observation by the X-ray diffraction method or a scanning electron microscopy equipped with an energy dispersion type X-ray analyzer.

In the above way, the Zn alloy particles having physical fracture facets and/or cracks of the present invention can improve the corrosion resistance and rust prevention to an unprecedented extent by imparting at least one physical fracture facet and/or cracks and simultaneously controlling the chemical composition of the metal particles.

Further, the Zn alloy particles having physical fracture facets and/or cracks of the present invention can simultaneously give a more superior corrosion resistance, rust prevention, and coatability by making the shape of the particles having fracture facets a polyhedron close to a nonflat shape (cracks not included at the surface) having two or more facets.

From the viewpoint of the improvement of the corrosion resistance and rust prevention, the greater the number of physical fracture facets, the better, but with just one or no fracture facet, while the reason is not clear at the present point of time, the effect of improvement of the effect greatly varies.

Further, when the average aspect ratio is more than 2 and the shape is extremely flat, the work efficiency at the time of coating falls, so this is not preferred.

Therefore, the shapes of the particles are defined as being polyhedrons close to non-flat spheres (average value of aspect ratio of 1 to 1.5) having two or more facets.

This range of shapes defines the Zn alloy particles in the material state and does not define the shape of Zn alloy particles in the case of Zn alloy particles absorbing the moisture etc. in the air and coagulating and coalescing before actually being used mixed in paints or in the case of curing and coalescing on the steel material as a coat.

At the time of production or storage, small relief shapes form at the Zn alloy powder surface, but the changes in shape due to these are not out of the range of spherical or oval shapes with an average value of the aspect ratio of 1 to 1.5.

Next, the method of production of the Zn alloy particles of the present invention will be explained.

When producing the Zn alloy particles having physical fracture facets and/or cracks of the present invention, first primary particles comprised of the chemical composition defined in (1) or (2) are produced, then the primary particles are made to impact each other or impact a solid to fracture the primary particles and form physical fracture facets and/or cracks on the primary particles of the Zn alloy particles.

That is, even among the fracture facets and/or cracks, a rolling force and shearing force greatly act. It is extremely difficult to satisfy the value of the aspect ratio of the present invention and obtain Zn alloy particles having physical fracture facets and/or cracks.

When producing the Zn alloy particles having physical fracture facets and/or cracks of the present invention, first primary particles comprised of the chemical composition defined in claim 1 or 2 are produced, then the primary particles are made to impact each other or impact a solid to fracture the primary particles and form physical fracture facets and/or cracks on the primary particles of the Zn alloy particles.

When using impact to obtain physical fracture facets and/or cracks, a large individual mass enables the kinetic energy contributing to physical surface fractures and/or cracks at the time of impact to be secured, but experimentally, if the average particle size of the primary particles is over 1000 μm, the work time for obtaining the maximum average particle size of 200 μm aimed at by the present invention remarkably increases.

On the other hand, Zn alloy particles having physical fracture facets and/or cracks and having a minimum average particle size of 0.05 μm can be obtained by using primary particles having an average particle size of 0.05 μm or more and increasing the number of times of impact.

Due to the above reasons, in the present invention, the average particle size of the primary particles is made 0.05 to 1000 μm.

The average particle size of the primary particles, to improve the corrosion resistance and rust protection, is preferably 0.05 to 100 μm. Furthermore, to reliably improve the corrosion resistance and rust protection, it is preferably 0.05 to 30 μm.

Here, the “primary particles” mean Zn alloy particles before said impact or fractures. When obtaining the primary particles, the mist method, atomization method, ingot method, or any other method can be used.

Further, as the solid used for impacting said primary particles, in addition to a solid having a flat surface and/or curved surface, it is possible to use solid particles formed with a curved surface or solid particles formed with only flat surfaces.

Here, the material of the solid and solid particles has to be higher in hardness compared with the primary particles. Further, it preferably does not have reactivity when in contact under a water environment. As solids satisfying this requirement, a metal, sintered body, etc. may be mentioned.

In the production of Zn alloy particles by making primary particles impact each other or a solid and forming physical fracture facets and/or cracks on Zn alloy particles, it is possible to use a solvent as the medium for conveying the primary particles and more efficiently produce the Zn alloy particles having physical fracture facets and/or cracks targeted with a good efficiency.

The solvent is not limited in type so long as having a larger specific gravity compared with various gases including air. However, primary particles and Zn alloy particles given fracture facets and/or cracks are high in reaction activity, so the solvent has to be one with a low reaction activity with a metal having the chemical composition of the present invention.

When the solvent is particularly high in reaction activity and contains water as an impurity, the water has to be limited to 0.3 wt % or less.

In the present invention, the solvent is not limited, but toluene, xylene, or another organic solvent is suitable.

When utilizing the Zn alloy particles having fracture facets and/or cracks of the present invention, it is necessary to include 30% or more in the coat. If less than 30 mass %, the effect of the corrosion resistance etc. is not obtained.

The upper limit of the content is not particularly limited, but if over 85%, the resin ingredient becomes smaller and defects easily occur in the coat, so the upper limit is preferably 85% or less.

Note that the resin ingredient in the coat is preferably at least 15% so as to secure coating formability.

Furthermore, if the content of said Zn alloy particles is 30% or more, it is also possible to add other powder particles. For example, for the purpose of aesthetic design, it is also possible to add Al, stainless steel, or another metal powder, titanium oxide, zinc oxide, or another oxide powder, talc, stone powder, or another body pigment.

Furthermore, when utilizing Zn alloy particles having fracture facets and/or cracks of the present invention, it is possible to mix Zn metal particles having an average particle size of 0.05 to 50 μm into the Zn alloy particles in a range of x: 300.0 or less when the ratio, by mass %, of the amount of Zn alloy particles and the amount of Zn metal particles is 1/x.

The Zn metal particles referred to here mean particles comprised of Zn and unavoidable impurities.

Further, by mixing said Zn metal particles and Zn alloy particles having fracture facets and/or cracks for use for a paint pigment, it is possible to obtain remarkably superior corrosion resistance and rust prevention compared with a pigment using Zn metal particles alone like in the past.

However, when the ratio of mass % of the amount of Zn alloy particles and amount of Zn metal particles is 1/x, if x is over 300.0, the effect of the Zn alloy particles on the improvement of the corrosion resistance and rust protection is not sufficiently exhibited. Therefore, x was made 300.0 or less. If considering corrosion resistance and economy, x is preferably 1 to 120. Furthermore, if considering the mixing stability, x is preferably 1 to 30.

In the present invention, the average particle size of the Zn metal particles used for the mixing is made 0.05 to 50 μm. The effect of improvement of the corrosion resistance in the present invention is recognized in a range of average particle size of the Zn metal particles mixed of 0.05 to 300 μm, but considering industrial stability and the inexpensively available average particle sizes, the average particle size of the Zn metal particles was made 0.05 to 50 μm.

On the other hand, the effect of mixing the Zn alloy particles having physical fracture facets and/or cracks of the present invention and Zn metal particles can be analyzed by the content of Mg contained in the total rust prevention pigment.

When the total, by mass %, of the mixed particles of the Zn alloy particles having physical fracture facets and/or cracks of the present invention and Zn metal particles is 100%, the content of Mg used may be made 0.01 to less than 30%.

The content of Mg may be suitably applied in accordance with the object, but 0.1 to 20%, where the effect of mixing Zn alloy particles having fracture facets and/or cracks and Zn metal particles becomes the most remarkable, is preferable from the viewpoint of the stability of the effect of improvement of the corrosion resistance. Further, if considering economy, 0.5 to 15% is more preferable.

Note that in the present invention, the type of the resin ingredient of the paint, that is, the base resin, is not particularly limited. Either an inorganic-based or organic-based binder may be utilized.

The present invention is not particularly limited, but when inorganically based, alkali silicate, alkyl silicate, etc. may be suitably used, while when organically based, an epoxy-based resin, modified epoxy resin, acryl-based resin, urethane-based resin, polyester resin, etc. may be suitably used.

Further, regarding the type of formulation of the curing agent as well, the single-liquid curing type, the two-liquid curing type, or other types using the effects of several liquids may be suitably used in accordance with the object.

Regarding the curing method as well, ordinary temperature curing, heated curing, UV curing, electron beam curing, water curing, etc. may be suitably used in accordance with the object.

The steel material and steel structure coated with the high corrosion resistance rust prevention paint of the present invention are not particularly limited, but to coat the paint of the present invention on the surface of a steel material or steel structure to obtain corrosion resistance or corrosion protection, the coat thickness has to be 2 μm or more.

Further, the ferrous metal materials and steel structures covered by the present invention are materials and structures coated with the high corrosion resistance rust prevention paint of the present invention to a thickness of 2 μm to 700 μm and are not limited by chemical composition of the steel material, shape, or structure. Further, they include ones with surfaces on which other corrosion protection means are jointly used.

Note that if considering economy and painting work efficiency, the thickness of the high corrosion resistance rust prevention paint of the present invention is preferably 2 to 300 μm.

While not limiting the present invention to this, as the painted objects, cast iron, carbon steel, specialty steel, stainless steel, corrosion resistant steel, welded joints, etc. may be mentioned. As shapes, thick-gauge steel plate, thin-gauge steel plate, steel pipe, steel rods, etc. and shapes obtained by working these may be mentioned.

Note that in the present invention, as other corrosion protection means able to be jointly used with, there are plating, painting, galvanic corrosion prevention, etc.

EXAMPLES Example 1

Below, examples will be used to explain the present invention.

Under the conditions shown in Tables 1 to 14, painting test pieces were prepared. Primary particles of Zn alloy particles were prepared using the gas atomization method.

Furthermore, Zn alloy particles were made to impact each other or Zn alloy particles were made to impact a solid to prepare secondary particles or Zn alloy particles were added to toluene or xylene with a moisture content of 0.3% or less to make a slurry and the method of making the particles impact each other or impact a solid was used to prepare secondary particles so as to produce Zn alloy particles having physical fracture facets and/or cracks.

Zn alloy particles without physical fracture facets and/or cracks were produced by a beads mill or ball mill. The average particle size was measured by the laser diffraction scattering method. Therefore, the particle size was evaluated as the sphere equivalent diameter.

Further, the average value of the aspect ratio was measured by observation of 50 to 100 randomly extracted particles by a scan type electron microscope.

Paints were prepared by the general method. For the base resin, that is, the binder, a commercially available alkali silicate or alkyl silicate resin inorganic binder or four types of commercially available organic binders were used.

The prepared paints were applied to steel plates by brushing or spraying. As an evaluation test, a salt water spray test shown in JIS K5600 (5% NaCl sprayed at 35 degrees Celsius) was performed.

As painting test pieces, 150×70×3.2 mm test pieces were used. At the bottom of the test pieces, cross-cuts were made by a cutter.

The corrosion resistance was evaluated by the time for formation of red rust from the test piece surface. Formation at 900 hours or less was evaluated as “poor”, formation at 900 to 2000 hours as “good”, and formation at 2000 hours or more as “very good”.

From Tables 1 to 14, it is learned that the painting test pieces using the Zn alloy particles of the present invention exhibit superior corrosion resistance both with inorganic-based binders and organic-based binders.

Example 3

Zn alloy particles with the chemical ingredients shown in Tables 27 to 42 were produced in the same way as in Example 1. The rest is the same as Example 1.

The Mg solid solution phase was identified by the X-ray diffraction method. Further, the Zn—Mg intermetallic compounds were identified by analysis of the ratio of composition of the Mg and Zn at the physical fracture facets or crack surfaces by the X-ray diffraction method or by observation by a scanning electron microscopy with an energy dispersion type X-ray analyzer.

When the content of Mg was less than 16 mass %, at the detected X-ray diffraction peaks, the Mg₂Zn₁₁ or MgZn₂ peaks were the main peaks. When the content of Mg was 16 mass % or more, the ratio of composition of the Mg and Zn at the physical fracture facets or crack surfaces was analyzed by the X-ray diffraction method or by observation by a scanning electron microscopy with an energy dispersion type X-ray analyzer whereupon the presence of Mg₂Zn₃, MgZn, or Mg₇Zn₃ was confirmed.

From Tables 27 to 42, it is learned that due to the presence of the Mg solid solution phase and Zn—Mg intermetallic compounds at the surfaces of the particles including fractured parts, the painting test pieces using the Zn alloy particles of the present invention are improved in corrosion resistance and rust protection regardless of the type of base resin, that is, both for inorganic-based and organic-based binders.

Example 4

Zn alloy particles with the chemical ingredients shown in Tables 43 to 57 were prepared in the same way as in Example 1. The rest is the same as Example 3.

MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, or, Mg₇Zn₃ were identified by analysis of the ratio of composition of the Mg and Zn at the physical fracture facets or crack surfaces by the X-ray diffraction method or by observation by a scanning electron microscopy with an energy dispersion type X-ray analyzer.

Further, the number of facets of the Zn alloy particles was measured by observing 50 to 100 randomly extracted particles by a scan type electron microscope.

From Tables 43 to 57, it is learned that due to the surfaces of the particles including fractured parts having, as intermetallic compounds, at least one type of compound of MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃ or due to the number of facets being two facets or more, the painting test pieces using the Zn alloy particles of the present invention are improved in corrosion resistance and rust protection regardless of the type of base resin, that is, both for inorganic-based and organic-based binders.

Example 5

Zn alloy particles with the chemical ingredients shown Tables 58 to 75 were produced in the same way as in Example 1. Zn metal particles of an average particle size 0.05 to 50 μm were mixed in the paints. The rest is the same as Example 1.

From Tables 58 to 75, it is learned that the painting test pieces using the Zn alloy particles and Zn metal particles of the present invention are improved in corrosion resistance and rust prevention regardless of the type of base resin, that is, both for inorganic-based and organic-based binders.

Zn alloy particles with the chemical ingredients shown in Tables 92 to 108 were produced in the same way as in Example 5. At the time of preparing the paint, four commercially available organic-based binders were used. The rest is the same as Example 5.

The Mg solid solution phase was identified by the X-ray diffraction method. The Zn—Mg intermetallic compounds were identified by analysis of the ratio of composition of the Mg and Zn at the physical fracture facets or crack surfaces by the X-ray diffraction method or by observation by a scanning electron microscopy with an energy dispersion type X-ray analyzer. The composition was MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, or Mg₇Zn₃.

From Tables 92 to 108, it is learned that due to the surfaces of the particles including fractured parts and/or cracks having a Mg solid solution phase and Zn—Mg intermetallic compounds, the painting test pieces using the Zn alloy particles of the present invention are improved in corrosion resistance and rust protection.

Example 8

Zn alloy particles with the chemical ingredients shown in Tables 109 to 125 were produced in the same way as in Example 5. The rest is the same as Example 5.

MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃ were identified by analysis of the ratio of composition of the Mg and Zn at the physical fracture facets or crack surfaces by the X-ray diffraction method or by observation by a scanning electron microscopy with an energy dispersion type X-ray analyzer.

The number of facets of the Zn alloy particles was identified by observation of 50 to 100 randomly extracted particles using a scan type electron microscope.

From Tables 109 to 125, it is learned that due to the surfaces of the particles including fractured parts and/or cracks having as intermetallic compounds one or more types of compounds of MgZn₂, Mg₂Zn₁₁, Mg₂Zn₃, MgZn, and Mg₇Zn₃ or due to the number of facets being two facets or more, the painting test pieces using the Zn alloy particles and Zn metal particles of the present invention are improved in corrosion resistance and rust protection regardless of the type of base resin, that is, both for inorganic-based and organic-based binders.
